I planted some Red Russian Kale about three years ago, and every year I just let a couple go to seed. The seeds usually fall quite close together and close to the parent plant. This year the plants didn't get very big, so I'm thinking they might be needing some fresh feilds.
I will dig any new seedlings up from these ones, that are just starting to go to seed, and move them to my new brassica bed (when I have made it)
I have a favourite salad recipe that I like to make with Red Russian Kale: Pipi's Soba Noodle Salad.
For the salad: combine 300g peeled, chopped and roasted red kumara, 2 bundles of dried soba noodles - cooked in plenty of salted boiling water and then drained. 2 avocados cubed, 100g kale leaves - stalks removed, finely sliced and then squashed with your hands, and a good handful of chopped mint.
For the dressing: In a jar, combine the juice of 3 oranges and 1 lime, 4 Tabs avocado oil, 1.5 Tabs soy sauce, 1.5 Tabs sesame oil, a pinch of chilli flakes and 1/2 tsp salt. Shake well and dress the salad just before serving.
